C2 cylinders on earlier case

Anyone here with experience using C2T cylinders in an earlier case (e.g. 1986 3.3 case)? Assuming you used o-rings to seal, any issues?

I lost a lot of my paperwork when my computer crashed, but the C2T P&C are the fully finned ones correct? If so, that's what I used on my rebuild (87). We used the o-rings (and possibly a copper gasket IIRC). I'll have to ask my buddy to be sure, but there is a certain method to installing them to prevent leaks.

Yes, the C2T cylinders are fully finned. I used the C2T's in my '85 930, used the viton cylinder o-rings for the spigot bore and used the copper based shims to maintain the factory deck height. Be aware that the infamous cylinder/head oil seepage arose from these cylinder/head combination's in instances where no head gasket is applied. I had very small signs of that on my engine. I would recommend using either the factory gasket or have the heads and cylinders modified by Steve Weiner to get a perfect mating surface.

Thanks for the responses. Yes, I have the fully finned C2T Ps&Cs. The earlier case mating surface is different from the C2T case around the head stud holes. Similar difference around the heads. Just wanted to be sure that time has proven this setup to work well. Planning to use the viton o-rings and copper gaskets so seems that should work well.

Oh yeah, we sprayed some copper type gasket maker on the copper gaskets to help prevent leaks.

I love that spray for any solid metal head gasket. Even on water cooled engines I've had good luck at 14:1. Some say don't use it, but in my hands I'd rather than not.

Really? Has anyone else used the tacky copper spray on cylinder head gaskets? I would think that it would create inconsistencies in between the head/gasket or barrel/gasket or worse, crystallize and blow out.
